The words expressing the positions and directions described in the present utility model are described by taking the drawings as an example, but can be changed according to the needs, and all the changes are included in the protection scope of the present utility model.

Referring to fig. 1, the utility model discloses a steel bar bending jig which comprises a base 1, a matching piece 2, a movable piece 3, a first limiting piece 4 and a second limiting piece 5.

Wherein the base 1 has a substantially rectangular structure, the base 1 having a first end 11 and a second end 12 arranged in a longitudinal direction.

The fitting 2 is arranged at a first end 11 of the base 1, and the fitting 2 may be connected to the base 1 by means of a shaft, as an example, so as to be fixed at the first end 11.

The movable member 3 is disposed at the second end 12 of the base 1 and can move along the length direction of the base 1, and typically, the movable member 3 needs to be connected to a driving device (not shown), such as a compression bar mechanism, a hydraulic driving mechanism 6, an electric driving mechanism, etc., so as to control the movable member 3 to move linearly on the base 1.

And, the movable member 3 is provided with a press bending groove 31 at a side facing the mating member 2, and the press bending groove 31 may be an arc-shaped groove, and when the movable member 3 moves toward the mating member 2, the reinforcing bars placed between the movable member 3 and the mating member 2 are deformed and bent by being pushed at the press bending groove 31 (see fig. 3).

The first stopper 4 is disposed between the fitting 2 and the press bending groove 31 to thereby limit the stroke of the press bending groove 31 to press the reinforcing bar, thereby limiting the bending angle of the reinforcing bar to be press-bent. In short, the closer the first stopper 4 is to the fitting 2, the smaller the bending angle of the reinforcing bar is. The position of the first limiting part 4 is determined according to the processing requirement required by the steel bars, and under the condition of determining the position of the first limiting part 4, each steel bar to be bent can be subjected to the same limiting bending, so that the consistency of the bending degrees of different steel bars is ensured.

The first limiting member 4 has a columnar structure, and may be screw steel, round steel, or the like. In the application, as the reinforcing steel bar only has the requirement of one bending degree, the first limiting part 4 is vertically welded on the base 1, so that the self position is fixed, and the effect is stable and reliable.

In other embodiments, at least one mounting hole 13 may be further disposed between the mating member 2 and the movable member 3, where the mounting holes 13 are uniformly spaced on the upper end surface of the base 1, and the first limiting member 4 is detachably disposed in the mounting hole 13, for example, the first limiting member 4 may be inserted into the mounting hole 13, screwed, and so on, and by adjusting the position of the first limiting member 4, the reinforcing steel bar may obtain different curvatures.

The second limiting piece 5 is arranged on one side of the base 1, and the second limiting piece 5 is used for limiting the length position of the steel bar to be bent, so that the consistency of the bending positions of the steel bar is ensured.

The second limiting part 5 is of an L-shaped structure, and can be made of square steel. In the present application, the second stopper 5 includes a stopper portion 51 and a connecting portion 52. Wherein, the stopper portion 51 sets up one side of base 1 width direction, and stopper portion 51 is used for the end of butt waiting to press curved reinforcing bar, and this makes every reinforcing bar place the part between mating member 2 and the movable part 3 in the same position, also can guarantee the uniformity of bending position after the bending. The connecting portion 52 is connected to the stopper 51 and the base 1, and fixes the second stopper 5 to the base 1.

In some other embodiments, as shown in fig. 2, the length of the connection portion 52 is adjustable to flexibly adjust the bending position of the reinforcing bars. Illustratively, the connection portion 52 includes a fixed tube 521, a movable tube 522, and a tension bolt 523. The fixed pipe 521 is welded and fixed with the base 1, the movable pipe 522 is welded and fixed with the stop portion 51, the movable pipe 522 is partially slidably disposed in the fixed pipe 521, the elastic bolt 523 penetrates the pipe body of the fixed pipe 521 and can abut against the pipe body of the movable pipe 522, and the overall length of the connecting portion 52 can be flexibly adjusted by screwing the elastic bolt 523, so that the bending position of the steel bar to be bent is changed.

The steel bar bending jig has the advantages that the whole structure is simple, bending operation is convenient and fast, all components are materials which are easy to obtain on a construction site, the manufacturing cost is low, and the jig is suitable for popularization and application.

Referring to fig. 3, in some embodiments, the mating element 2 is a V-wheel. As the part contacted with the steel bar, the V-shaped wheel can enable the steel bar to be always embedded in the V-shaped wheel surface, thereby preventing the steel bar from moving or shifting, ensuring the bending quality of the steel bar and improving the construction safety.

Referring to fig. 1 and 3, in some embodiments, rollers 32 are provided on both sides of the notch of the clinching groove 31. In the bending process, if the steel bars are directly contacted with two sides of the bending groove 31, larger friction force is generated at the contact part, so that the force application difficulty is increased, the bending process is unsmooth, the friction force at the contact part is reduced by arranging the roller 32, and the construction operation is convenient. In addition, the inner side of the steel bar can be subjected to tensile stress and the outer side of the steel bar can be subjected to compressive stress during construction, and the roller 32 can play a role in dispersing stress, so that the stress condition of the steel bar is relieved, and the bending quality is ensured.
